10 Claims.

The invention relates to door constructions and refers more particularlyto baffle constructions for doors.

One of the objects of the invention is to provide a baffle between adoor and a guide therefor throughout substantially the length of thedoor. Another object is to so construct the baille that the door may bemoved longitudinally of a curved guide. A further object is to provide adoor with anti-friction means for engaging the guide. With these as wellas other objects in view, the invention resides in the novel features ofconstruction and combinations and arrangements of parts as more fullyhereinafter set forth.

In the drawings:

Figure 1 is a plan View of a door and guide construction embodying myinvention;

Figure 2 is an enlarged plan View of a portion thereof with the guide insection;

Figure 3 is a side elevation thereof;

Figure 4 is a cross section on the line 44 of Figure 2;

Figures 5 and 6 are views similar to Figures 2 and 3, respectively,showing a modification;

Figure 7 is a cross section on the line 77 of Figure 5.

The invention is particularly applicable to doors movable longitudinallyof curved guides, such as doors for airplane hangars, one of which isshown in the present instance.

1 is the door which may be supported by suitable means, such as wheels,and 2 is the guide which is in the nature of an angle iron having adepending flange terminating above the door. This guide has the straightand curved portions 3 and 4 respectively, along which the door ismovable.

For closing the space between the door 1 and the straight guide portion3 and forming an ef- 40 feotive weather seal therebetween, the door hassecured thereto a bafiie formed ofa section overlapping the dependingguide flange at its inner side and sections overlapping the dependingguide flange at its outer side and extending from opposite the ends ofthe first section to the ends of the door. These sections are soarranged that their adjacent ends overlap, but sufficient clearance isprovided there between to permitthe door to move along the curved guideportion 4. In detail, the section overlapping the inner side of thedepending guide flange comprises the roll carriers 5 secured to theupper portion of the door near its ends and extending upwardly therefromand the plate 6 extending between the roll carriers 5 and preferably inthe nature of an angle iron having one flange secured to the upper edgeof the door by the screws 7 and the other flange extending upwardlytherefrom. Rolls 8 having vertical axes are mounted upon theroll'carriers 5 to engage the inner side of the depending guide flange.The sections overlapping the outer side of the depending guide flangeare alike and each comprises the roll carrier 9 secured to the upperportion of the door adjacent a roll carrier 5, but at the opposite sideof the door and extending upwardly thereabove, and the plate 10extending from the roll carrier 9 to the adjacent end of the door. Thisplate 10 is in the nature of an angle iron and has one flange secured tothe upper edge of the door by the screws 11 and the other flangeextending upwardly therefrom. The roll 12 having a vertical axis ismounted in the roll carrier 9 in position to engage the outer side ofthe depending guide flange. The adjacent roll carriers 5 and 9 overlap,but are so positioned that their respective rolls 8 and 12 provideforthe necessary angular movement of the door to the depending guideflange, while the door is moving along the curved portion 4 of theguide.

The roll carriers 5 and 9 are preferably identical, but are reversed endfor end when applied to the opposite sides of the door. These rollcarriers are secured to the door by the bolts-13 and the nuts 14threaded upon these bolts, one of the bolts extending through both ofthe adjacent roll carriers and serving in securing the same to the door.Each roll carrier also preferably has -a flange portion extending overthe upper edge of the door and secured thereto by the screws 15. In themodification shown in Figures 5, 6 and 7, a roll carrier 16 is pivotallymounted at the outer edge of the door near each end. Each of these rollcarriers is set into the recess 17 in the upper edge of the door and hasthe pin 18 extendr ing vertically and journaled in the supporting block19 secured in the upper portion of the door. The portion of the rollcarrier extending upwardly above the door is formed in two segments 20which are spaced apart to receive therebetween the depending guideflange and the edges of these segments are preferably provided with theparallel flanges 21. 22 is a plate secured to the upper edge of the doorand extending between the roll carriers 16 and overlapping the flanges21 of these roll carriers and the depending guide flange at its innerside. This plate may be formed and secured to the door in the samemanner as the plate 6. 23 is a plate secured to the upper edge of thedoor and extending from each roll carrier 16 to the end of the door,this plate overlapping a flange 21 of the roll carrier and the dependingguide iiange at its outer side. Each of these plates 23 may be formedand secured to the door in the same manner as each of the plates 10.Rolls 24 having vertical pivots are mounted in the segments 20 of eachroll carrier 16 to engage opposite sides of the depending guide flange.

From the above description it will be readily seen that I have provideda construction of baffie between a door and an adjacent guide thereforwhen the door is in closed position which extends throughout the lengthof the door and which provides for movement of the door along a curvedguide. It will also be seen that the construction is such thatanti-friction bearings for engaging the guide may be used to facilitatemovement of the door from its closed to its open positions or viceVersa.

What I claim as my invention is:

1. The combination with a guide having straight and curved portions anda door movable longitudinally of said guide, of a baflle extendingthroughout substantially the length of said door and comprising asection overlapping said guide and located at the inner side thereof,and sections overlapping said guide and located at the outer sidethereof and extending beyond the ends of said first mentioned section.

2. The combination with a guide having straight and curved portions anda door movable longitudinally of said guide, of a bafiie extendingthroughout substantially the length of said door and comprising asection overlapping said guide and located at the inner side thereof,

and sections overlapping said guide and located at the outer sidethereof and extending beyond the ends of said first mentioned section,and antifriction means at the adjacentends of said sections and engagingopposite sides of said guide.

3. The combination with a guide having straight and curved portions anda door movable longitudinally of said guide, of a baffle extendingthroughout substantially the length of said door and comprising asection overlapping said guide and located at the inner side thereof,and sections overlapping said guide and located at the outer sidethereof and extending beyond the ends of said first mentioned section,said sections comprising plates and roll carriers secured tosaid door.

4. The combination with a guide havingstraight and curved portions and adoor movable longitudinally of said guide, of a bafiie extendingthroughout substantially the length of said door and comprising rollcarriers secured to said door near the ends, thereof, a plate secured tosaid door and extending between said carriers at one side of said guide,and plates at the opposite side .of said guide secured to said door andextending therefrom, roll carriers secured to said door and overlappingsaid guide at one side thereof, a plate secured to said door andextending between said roll carriers and overlapping said guide, rollcarriers secured to said door adjacent to said first mentioned rollcarriers and overlapping the opposite side of said guide, and platessecured to said door and overlapping said guide and extending from saidlast mentioned roll carriers to adjacent the ends of said door.

6. The combination with a guide and a door movable longitudinally ofsaid guide and spaced therefrom, of roll carriers pivotally carried bysaid door near the ends thereof and overlapping said guide at oppositesides thereof, a plate secured to said door and extending between saidroll carriers and overlapping one side of said guide, and plates securedto said door and overlapping the opposite side of said guide andextending from said roll carriers to adjacent the ends of said door.
